Flexible & User-friendly Easy wiring Screwless terminal block (control terminal block). Modbus communication as standard – two communication terminals are provided. Therefore daisy chain wiring is easy to realize. Heat sink extraction It is easy to place the cooling fans to the outside of the cabinet since the L-shaped brackets are separate parts. L-shaped bracket Wall Wall 0 – 10 V in / out and 4 ~ 20 mA in / out are easily switched by DIP switch. J 2 analog inputs (3 inputs in total) J 2 analog outputs Fulfilling lifetime prediction functions Electrolytic capacitor of power circ

Improved efficiency with 24 VDC supply In addition to normal power supply (R0, T0), external 24 VDC control power can also be applied as standard. Parameter setting is also available if the main power is turned off meaning operational efficiency is increased and standby power is reduced. It will also contribute to energy savings. Connecting to the PLC and settings via PC configuration software are also available. Quick diagnose of failure occurrence P1 can also store internal data to the internal memory on a continuous basis. It can also upload data to the PC when an error occurs – making...

SJ-P1 Smooth Operation and Precision “Smooth operation” can be easily achieved High starting torque from the low speed area supports the smooth drive of heavy load. Reduction of the load swing Disable function Enable function Motor rotation rate Motor rotation rate Output torque (%) Decreasing overshoot and undershoot contributes to smooth and stabilized operation with less shock. (*Sensorless vector control with ND rating) Steady operation for crane, lift, transport etc. Trip can be prevented by smooth driving to support steady operation of crane and conveyer for better productivity. “High...

Induction motor & permanent magnet motor can be controlled with one inverter series The SJ-P1 inverter can be used to drive both induction motors (IM) and permanent magnetic motors (PM). PM motors are energy efficient and make effective use of available space. Thanks to the over-current trip level setting, demagnetization of PM motors can be suppressed. Multi-rating to support space and cost savings Triple-rating for IM motor for various applications is available. Also dual-rate for PM motor control can be selected. Multi-rating helps to save space and costs. Rating VLD (Very Light Load)...
